I think that it is important to note that this only works if the font you are using has the € symbol available. For instance, I am working on a customer's menu, and they designed it using AG Buch BQ, which has no € symbol in the font.

There are several limitations. As you said the font must have that glyph available and it works on an American English keyboard. This may work on other keyboard layouts, but I can't attest to that.

@gavin every app I know will substitute a font that does include Euro if the currently active font is missing it.

@Tomg, I am working in InDesign, and InDesign did not do what you are talking about for this font. Although their is some amount of font substitution possible, in a Graphic Design environment, where you are sending customer files to a printing press, messing around with the customer fonts is generally frowned upon.

Thanks for that info, Gavin. I didn't know that InDesign still worked this way. Kind of defeats the purpose of using the Unicode standard, but I suppose it's useful in terms of letting users know their chosen font is not adequate for their text.

Once you have the keyboard viewer enabled, go to the keyboard menu in your menu bar (it will look like either a picture of a keyboard or a flag representing the keyboard layout you have selected) and chose Keyboard Viewer. A window will appear with a picture of your keyboard. If you hold down the option, shift, or option and shift keys, it will show you what the keys on your keyboard do with those modifier keys pressed.

[Edit] Tested with British & Irish, [both use alt/2] US, Canadian & British-PC [use alt/shift/2] The alternate in each case gives ™
Very similar to the British/US 'pound' symbol, swapped between shift/3 or alt/3 depending on keyboard.

Suspect it depends on the locale you are using, what hardware keyboard you are using etc, it's not going to be the same for everyone. This one works for me, with a UK keyboard. Perhaps the other answer is using a US layout.

An option to use once you know how to get the € symbol is to create a text shortcut for the symbol on your Mac for faster typing. You can do this using text replacement.

To get started, follow these steps (also see image below for reference):

Launch System Preferences and click on Keyboard (Language & Text on previous versions of OS X).

Click on the Text tab.

The Replace and With columns appear. Click on the + button at bottom-left to add a new text shortcut, which opens a text field for you to type your trigger text, for example euro.

Press ⇥ tab key or mouse over to the adjacent text field (under the With column) and enter the actual € symbol. This becomes the resulting replacement text.

And you’re done. The next time you enter “euro” it will be replaced automatically with “€”. But you can always press the Esc keyboard button (to cancel the text replacement) if you actually want to type out the word “euro”.

This also works for iOS devices under Settings → General → Keyboard → Shortcuts.

Please note that this does not work automatically in every app. I’ve confirmed it works on iMessage, Notes, Reminders, Mail.

For iWork (e.g., Pages, Keynotes, Numbers) you’ll have to add the shortcuts as they use their own text replacement functionality. For example in Pages, click on the Pages menu item, then click on Auto-Correction tab, and add any text shortcuts in the same way as above. Here you can even choose to toggle (on or off) which text shortcuts you want to be active.
